Properties of friction:
1. It is a contact force i.e. it acts on the surfaces which are in contact.
2. It's magnitude is independent of contact area.
3. It depends on the roughness of the surfaces in contact.
4. It acts in the opposite direction of motion/ impending motion.
5. It never initiates motion.
